    Pyle Pro PDC21 reviews

    PDC21 Direct Box is rated 3.9 out of 5 by 25.
    Rated 3 out of 5 by from It got the job done but won't buy more 3 stars for working and being value price, but minus 2 stars for durability. Sound Quality is ok for the price but not as good as a Radial or Whirlwind, and requires some more gain to get the same level. The XLR connector feels very, very cheap. I would not expect to use this box for more than a weekend as the connectors break very easily. You get what you pay for. If your in need a Di box I'd suggest buying one from another brand, as paying double the price of this one will likely result in a box that will last you at least twice as long. Don't risk the sound quality of your show on something cheap like this!

    Rated 4 out of 5 by from Does exactly what it says I am using 6 of these to get rid of ground loop hum when sending an unbalanced RCA output sound from a polycom video conference to a MOTU and/or Nexia CS digital audio mixer. Works great! The attenuation setting works well, although the ground on/off button doesn't seem to have any affect on my situation. Lowest price solution out there by a long shot! Only thing I didn't like was I had to use ended cables... a lot of the integration I do uses barrier strips/pheonix connectors/euroblocks ... which are screw terminals meant for bare-end wires. I would love to see an integrators version of this with screw terminal input outputs rather than the XLR and 1/4 phono plugs.

    Rated 3 out of 5 by from Risked and lost As a simple box to balance a signal, this box works well enough. I bought it as a DI for a guitar, assuming that it had a transformer inside with a high-impedance primary. The input impedance is 50K Ohms not high enough for a guitar. I expected 10M. If you are wanting to record a high impedance instrument, then buy a preamp with 10M input impedance. The ground float is a very nice feature. The connectors are of high quality, which was unexpected in a box priced so low.

    Rated 4 out of 5 by from Decent For Price I was super excited to find these boxes at this price. Direct boxes go walking from my facility, and the opportunity to pick a few up for under $10 each was something amazing that I didn't even think was possible. When I got them (by the way, B&H's customs service is AWESOME if you live in Canada) I was eager to put them head-to-head against the other DI's I had in the house, which were a no-name passive DI and a Behringer active DI. The only difference I could really discern is that these Pyle Pro boxes don't put out nearly as hot a signal as most DI boxes do. So they need a little more gain. But other than that... for the price... I can't complain. To find a passive DI with a ground lift AND an attenuator (which works great) for under $10 is a STEAL.

    Rated 1 out of 5 by from DO NOT BUY first, thanks BH for the quick shipping, two days to Toronto. Bought 5, 3 DOA, 1 has finicky att switch so that sound cuts in and out at random. Emailed BH using contact us at bottom of page, no response after 7 days. probably not a good idea to shop from Canada.

    Rated 5 out of 5 by from PDC21 Direct Box by Pyle Pro This is one great item to use on stage with the guitars. Love it!

    Rated 4 out of 5 by from Good Utility Box This is an inexpensive little direct box that I use in small installations to convert from balanced to unbalanced signal or unbalanced to balanced signal. Generally built pretty solid but I haven't used this unit on the road. No doubt it gets the job done. Only gets 4 stars because while it works fine and will continue to, you get what you pay for in terms of the transformer.

    Rated 5 out of 5 by from Sturdy. Plain. Simple. Effective. This little box has everything a nice DI has to have and at a price that won't offend your wallet. I wanted different DIs for bands I make sound for in different venues and I was tired of hauling those expensive Radial around. I just went for a couple of these and I must say these look pretty sturdy. Even has different Pad values!
